Title: Rolling mill of wire rod
Inventor: FUKUOKA SHINGORO
IPC: B21B13/02
Filed: 1984-12-24
Abstract: PURPOSE:To reduce remarkably the number of annealings and to improve the productivity by rolling a rolling stock under a large reduction rate of area by providing the calibers of specific conditions for forming a rolling gap between them to a pair of rolling rolls arranged oppositely. CONSTITUTION:The calibers 14, 14' of rolling rolls 12, 12' are mutually nonsymmetrical with respect to a line (b), which passes through the middle point M of a line (a) connecting both caliber edges 14a, 14b and is perpendicular to the roll axial line X. Therefore, the stock is slanted with respect to the axial line X after rolling. The stock is rolled from various angles by arranging plural pairs of rolls having different slants respectively. The stock is rolled under a large reduction rate of area without spreading its width, because the rolling gap 16 is closed; then the productivity is improved. Further, the roll gap 16 is formed point-symmetrically with respect to the middle point M of the line (a) connecting the caliber edges between rolls 12, 12'. By enlarging the angle of its symmetrical line with respect to the roll axis X and reducing its slant as small as possible, the twisted angle of stock can be reduced when supplied to the next stage.

IPC: F01P5/02
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To improve a fan efficiency by reducing loss due to a speed component in a turning direction in the cooling blow of a centrifugal fan. SOLUTION: Cooling blow enters an engine room 1 from the outside of the engine room 1 through an cooling air intake 7 and passes through a heat exchanger such as an intercooler 6a, an oil cooler 6b and a radiator 6C and then is throttled by a suction pipe 8a and enters a centrifugal fan 4. High speed cooling blow is given by a centrifugal force of the blades of the centrifugal fan 4 rotating around a shaft a speed component in a turning direction which turns in a circumferential direction in the outer circumferential region of the radial direction of the fan outlet and a nose 12 made in the outer circumferential region guides the cooling blow in an axial direction while blocking it in a circumferential direction and reduces a speed component in a turning direction to prevent turning, thereby recovering static pressure.

Title: Low porosity carbon material and its production
Inventor: FUJIURA TAKATSUGU
IPC: C01B31/02
Filed: 1994-11-04
Abstract: PURPOSE: To industrially advantageously produce a carbon material having remarkably reduced porosity by powdering specified self-fusible carbonaceous mesophase particles and compacting the resultant powder without using a binder. CONSTITUTION: Self-fusible carbonaceous mesophase particles having a ratio of <0.01 as the atomic ratio of hydrogen and oxygen to carbon are powdered to <=5μm average particle diameter and the resultant powder is compacted without using a binder and is fired to obtain the objective carbon material. This carbon material is a low porosity carbon material having <=30mm<3> /g total pore volume. The mesophase particles ensure a very high yield of carbonization and hardly generate gas in a firing-carbonizing process while maintaining the stickiness of mesophase pitch. Since the carbonaceous particles can be prepd. by an easy process at a low cost and the powder can be compacted without using a binder and ensures stable high sintering power and a very high yield of carbonization, this carbon material is industrially advantageously produced.

Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To provide a device for diagnosing a failure in a waveform shaping circuit capable of diagnosing a failure in the waveform shaping circuit reliably even in a single waveform shaping circuit. SOLUTION: Wheel velocity signals detected by four wheel velocity sensors FLS, FRS, RLS, and RRS each provided for a wheel are waveform-shaped by a waveform shaping circuit 14. In the case that output from the waveform shaping circuit 14 is absent for a predetermined period of time, a CPU 15 monitors the presence or absence of changes in the waveforms of the wheel velocity sensors inputted to an A/D converting part 17 at a frequency twice higher than a maximum wheel velocity frequency or more. Then on the basis whether there is a change by a predetermined value or more from a central value within a predetermined period of time in the voltage of a signal inputted to the A/D converting part 17, the waveform shaping circuit of wheel velocity is diagnosed.  In the case that there is a change in the voltage by a predetermined value or more from the central value within a predetermined period of time, it is determined that the waveform shaping circuit 14 is faulty.

Abstract: PURPOSE:To manufacture at low temperature and at a low cost by replacing La of a lanthanum chromite base material with a specified amount of Sr, Ba, or Ca, or by replacing part of Cr with a metal such as Mg. CONSTITUTION:A lanthanum chromite (LaCrO3) base material is used and part of La or Cr is replaced with Sr, Ba, Ca, or a metal such as Mg, and Ca is added in excess than a constant ratio. A liquid phase mainly comprising Ca is produced at around 1200 deg.C, and diffusion rate of cations in a grain boundary phase is increased and sintering capability is enhanced, and since the grain boundary is covered with the liquid phase, the evaporation of a chromium component is suppressed. Compared with conventional LaCrO3 base material, the dense product is obtained by sintering at low temperhen. When this material is used as a current collecting material in a cell of a fuel cell, the economical efficiency in the production process of the cell is enhanced.

Title: Ink feeder for fountain pen
Inventor: TOOMASU ROORINGEERU
IPC: B43K5/18
Filed: 1988-10-27
Abstract: PURPOSE: To prevent the breakage of an ink film between an ink supply device and a pen point even when writing pressure increases by extending the capillary ink send-out slit between the leading end part and main body of an inset to both sides of an ink supply device passing the center of the slit from the axial central surface thereof and rearwardly extending a part thereof. CONSTITUTION: The ink send-out slits opened to the pen point attaching surfaces formed between the leading end surface 21 of an inset 10 and the surface 33 of a main body 1 as well as the pen point attaching surfaces formed between the side wall parts 18, 19 of the inset 10 and the side wall parts 42, 41 of the main body 1 are provided symmetrically with respect to the axial central surface 25 of an ink supply device and left and right arms 41, 42 are separated from a base part 40 to expand toward the rear.  Therefore, when a pen point is attached, it is relatively largely opened and, even if the pen point is partially floated from the pen point attaching surface, the contact of ink send-out slits 40, 41, 42 with the pen point is well kept and, especially, since the ink is always sufficiently supplied from an ink holding space 30 becoming narrow toward the ink send-out slits 40, 41, 42, the ink film between the slits and the pen point is kept.

Title: Electrophotographic device
Inventor: UNO MUGIJIROU
IPC: A46B15/00
Filed: 1993-10-29
Abstract: PURPOSE:To keep electrostatic charge potential constant and to always obtain an excellent image by setting the effective resistance value of a whole system including an electrostatic charge part and a photoreceptor to twice or more as high as resistance value of the electrostatic charge part. CONSTITUTION:The surface of the photoreceptor 1 is uniformly electrostatically charged by the electrostatic charge part 2. The electrostatically charged surf ace is moved in accordance with the rotation of the photoreceptor 1 and exposed by an optical write part 3. Then, a latent image is formed at that part. Besides, the photoreceptor 1 is rotated and the latent image is selectively developed by toner by a developing part 4. Then, a toner image is formed. When the effective resistance value of the whole system including the charge part 2 and the photoreceptor 1 is defined as R1 and the resistance value of the charge part 2 is defined as R2, the relation of R1>2.R2 is attained. When the value R2 of the charge part 2 with respect to the value R1 of the whole electrostatic charge system is fluctuated within a very small range in such a way, the whole electrostatic charge system is not affected by it. Therefore, when the device is used within such a range that the effect is small, the electrostatic charge potential can be kept constant even in the case that an impressing voltage is fixed and the value R2 of the charge part 2 is fluctuated.
